It is not that surprising that the entire Kardashian clan is angry at Tristan Thompson for not only cheating on Khloe but doing so with several women while she was pregnant.

However, a new report has surfaced from PEOPLE magazine explaining that Khloe’s younger brother, Rob Kardashian, is the angriest member of the family.

While Rob is delighted to see baby True take over Khloe’s life and bring her joy, he is furious at the NBA player for breaking his sister’s heart and for humiliating her during such a delicate time in her life.

Dream’s father is also personally hurt by the scandal because he was fond of the basketball star and he trusted him.

The person close to the sock designer told the publication: “Khloé has always been there for Rob, and he hates that she was hurt — he knows what it feels like to be screwed over by someone you trusted.”

The insider added: “Rob will not forgive Tristan for this.”

Another source spilled the tea to Hollywood Life and revealed that Rob believes that Tristan duped the entire family and added: “Rob is super pissed that Tristan has broken his sister’s heart while she was pregnant. Rob cannot understand how this could have happened like that. Rob is angry because he feels that Tristan had him fooled. Rob feels like Tristan betrayed and lied to not only Khloe but the entire family. Rob is seriously pissed because he believed that Tristan was different, genuine and sincere. And, he feels like a fool for ever trusting Tristan the way he did.”

The second insider stated: “Rob is pleading with Khloe not to wait until the Tristan is done with the playoffs, but to break up with him immediately. Rob thinks it is disgusting what Tristan did to his sister. Rob feels Tristan not only embarrassed himself but Khloe and the entire family, so he wants his cut off now.”

One fan reacted to the news by saying: “Find a decent man to respect you. you deserve a better man. So sorry for what he is doing to you, hope you and your baby are doing good.”

Another commenter wrote: “Khloe you look beautiful, look what God gave you! Enjoy the most precious moments with your baby.”

A third follower shared: “Tristan: you know how long you’re going to last with her? When you run out of money.”
